Made for elite adventurers, the Therm-a-Rest NeoAir XLite NXT Sleeping Mat redefines ultralight comfort for all-season backcountry travel. With a 4-season ready 4.5 R-value, this advanced air pad delivers exceptional thermal efficiency thanks to its innovative ThermaCapture Technology and Triangular Core Matrix construction, which together reflect body heat and minimise heat loss. Boasting a Boosted Comfort design, it offers a plush 7.6cm thickness, allowing for personalised firmness and excellent sleep support on varied terrain. The mat is now 83% quieter than its predecessor, ensuring a quiet rest even when you shift in your sleep. In spite of its durability and warmth, the XLite NXT remains ultra-packable, folding down to about the size of a 1L water bottle. The user-friendly WingLock Valve system allows rapid one-way inflation and effortless deflation, with fine-tuned micro-adjustments for tailored comfort. Whether you're alpine trekking or embarking on an extended expedition, the NeoAir XLite NXT is a trusted companion that blends comfort, warmth, and portability like no other.
